Description
The application is that international filing date is on Dec 15th, 2006, and application number is 200680051488.4, and denomination of invention is the divisional application of " X-ray tomography inspection system ".
Technical field
The present invention relates to X-ray scanning.It has special application in the safety investigation of luggage, parcel and other suspicious objects, and it can be used for other suitable application equally.
Background technology
Roentgenometer calculation tomographic (CT) scanner is for the existing several years in the safety investigation on airport.Conventional system comprises around the X-ray tube of a certain axle rotation, and the arcuate X-ray detector of also rotating around same axle with identical speed.The transport tape that carries luggage on it is placed in and is positioned near the suitable hole of rotary middle spindle, and along with the rotation of ray tube is moved along this axle.The fan beam of X radioactive ray arrives X-ray detector array from radioactive source through examine object.
X-ray detector array records the intensity through the X ray of examine object on the several positions along its length.In each in the angle of many sources, record one group of data for projection.By the X ray intensity of these records, conventionally can utilize filtered back projection (filtered back projection) algorithm to form tomography (section) image.In order to produce the accurate tomographic image such as the object of sack or parcel, can show that requirement x-ray source penetrates the each plane by object.In above-mentioned configuration, the rotation sweep by x-ray source with and on carry object transmitter vertically move to realize this point.
In such system, the speed that can collect tomography X scanning depends on the rotational speed of the stand (gantry) that keeps x-ray source and detector array.In modern CT stand, whole ray tube-detector module and stand complete two and turn to four per second.This allows respectively the nearly tomographic scan of four times or eight times of collection per second.
Along with the development of prior art, the detecting device that the X-ray detector of monocycle has been encircled replaces.This make to adopt from the adjustment of single sweep machine and come filtered back-projection method scan and the many sections of reconstruct (slice) (being generally 8) simultaneously.Along with transmitter is through the continuous moving of imaging system, radioactive source has been described around the spiral fashion scanning of object mobile.This allows the more complicated cone-beam image reconstructing method of application, and it can provide more accurate volume image reconstruct in principle.
In another progress, in medical applications, show swipe electron beam scanning instrument (swept electron beam scanner), exempt thus the mechanical scanning campaign of x-ray source and detecting device, the substitute is around the continuous loop of the X-ray detector of inspected object, and owing to scanning the mobile x-ray source that electron beam produces around arc anode.This makes to obtain more quickly image than conventional sweep instrument.But because electron source is positioned on turning axle, therefore this swipe electron beam scanning instrument and transmission system are incompatible, transmission system itself approaches and moves abreast with turning axle.

Embodiment
With reference to Fig. 1～3, megaron luggage scanning system 6 comprises scanning element 8, and scanning element 8 comprises multifocal apart from x-ray source 10 and X-ray detector array 12.Radiographic source 10 comprises on each position separating on radiographic source and is configured in around a large amount of source points 14 in complete 360 ° of circular array of the axle X-X of system.Be appreciated that also can use and cover the array that is less than complete 360 ° of angles.
With reference to Fig. 1 a, in the plane vertical with the moving direction of transmitter, x-ray source 10 is made up of many source units 11, and these source units 11 are spaced apart with the substantially circular surrounding that is configured in scanning area 16.Each source unit 11 comprises and has the conducting metal rejector 13 of both sides and along the transmitter components 15 extending between rejector both sides.Above rejector 13, be supported with many grid elements of grid wire 17 forms vertical with transmitter components 15.In another plane of the side relative with transmitter components of grid wire, be supported with the many concentrating elements that focus on wire 19 forms.Focus on wire 19 parallel with grid wire 17 and be separated from each other with the interval identical with grid wire, each focusing wire 19 is aimed at in grid wire 17 corresponding one.
Focus on wire 19 supported on two support rails 21 that extend abreast with transmitter components 15, and separate with rejector 13.Support rail 21 is electric conductivity, and all focusing wires 19 are all electrically connected.In support rail 21 one is connected with connector 23 and thinks that focusing on wire 19 provides electrical connection.Each in grid wire 17 is extended below a side of rejector 13, and is connected with the respective electrical connector 25 that independent electrical connection is provided for each in grid wire 17.
Above grid wire 17 and focusing wire 19, be supported with anode 27.Anode 27 is formed as the bar of the copper that is generally plating tungsten or silver, and extends abreast with transmitter components 15.Therefore grid and focusing wire 17,19 extend between transmitter components 15 and anode 27.Electric connector 29 provides and being electrically connected of anode 27.
Except two grid wires 17 that are connected with positive potential, grid wire 17 is all connected with negative potential.These positive grid wires are from the extracted region electron beam of transmitter components 15, and by focusing on the focusing of wire 19, by direct electron beams, to the point on anode 27, this point forms this X ray source point to grid wire.Therefore the current potential of grid wire can be switched at any time, is movable so which to be selected to grid wire, and therefore to select at any time which point on anode 27 be movable X ray source point.
Radioactive source 10 therefore can be controlled as in the source point 14 in each from source unit 11 individually each produce X ray, and, again with reference to Fig. 1, from the X ray of each source point 14 by inside guiding for through the scanning area 16 in circular source 10.Control radioactive source 10 by control module 18 (its control is applied to current potential on grid wire 17 and controls thus each the X ray transmitting from source point 14).
Other suitable x-ray source designs have been described in WO 2004/097889.It is multifocal that to allow to use electronic control circuits 18 apart from x-ray source 10 be movable to select at any time which in multifocal many single X ray source point 14 in x-ray source.Thus, multifocal apart from X-ray tube by scanning electronically, in the situation that not having mechanical part physics to move, produce the illusion that x-ray source moves.In this case, the angular velocity of source rotation rises to while using conventional rotational x-ray pipe assembly irrealizable level at all.This rotation sweep rapidly can be converted into the data acquisition accelerating equivalently, and is converted into Image Reconstruction fast subsequently.
Detector array 12 is also circular, and on being configured in axially slightly the position in stray radiation source 10 around axle X-X.Radioactive source 10 is configured to guide the X ray of its generation to pass scanning area 16 towards the detector array 12 of a contrary side of scanning area.The path 18 of X-ray beam therefore along substantially or almost vertical with scanner axle X-X direction through scanning area 16, thereby near this axle, intersect.Be scanned the form that therefore presents the thin slice vertical with scanner axle with the volume of the scanning area of imaging.Radioactive source is scanned, and makes each source point transmitting corresponding period of X ray, and this emission period is arranged with the order of being scheduled to.Along with each source point 14 is launched X ray, can produce the signal of self-detector 12, this signal depends on the intensity that incides the X ray on detecting device, and the intensity data that tracer signal provides in storer.In the time that radioactive source completes its scanning, can process detector signal to form the image that is scanned volume.
Transport tape 20 from left to right passes imaging volume abreast with the axle X-X of scanner as shown in Figure 1.X ray scattering protective cover 22 be positioned at main x-ray system upstream and downstream transport tape 20 around, with the operator's radiological dose that prevents from causing due to the X ray of scattering.The end of X ray scattering protective cover 22 openings at them comprises lead rubber bar shaped curtain 24, makes the article 26 in checking in the time entering inspection area, be dragged through a curtain and in the time leaving, be dragged through a curtain.In the integrated system illustrating, show main electronic control system 18, disposal system 30, power supply 32 and the cooling frame 34 of the below that is arranged on transmitter 20.Transmitter 20 is configured to generally carry out work with constant transmitter speed by continuous scanning movement, and generally in imaging volume, have carbon fiber framework.
With reference to Fig. 4, disposal system 30 comprises electronic data acquisition system and realtime graphic reconfiguration system.The single X-ray detector 50 that X-ray detector array 12 comprises the many rows that are configured to simple linearity pattern (for example, 1x 16).Multiple ring patterns (for example, 8x 16) are also possible.Each detecting device 50 outputs depend on the signal of the intensity of the X ray of its detection.The outputting data signals of multipath transmission piece 52 multipath transmission each in X-ray detector 50 from input, executing data filtration, gain and offset correction, and this data layout is changed into high speed serialization stream.Select piece 53 to obtain input from all multipath transmission pieces 52, and only select the needed part of Image Reconstruction in whole X ray data.Select piece 53 also to determine unbated X-ray beam intensity I o (it will change with multifocal each X ray source point in X-ray tube) for suitable X ray source point, process the X ray intensity data Ix from multipath transmission piece 52 by forming result loge (Ix/Io), then with suitable 1-D wave filter, it is carried out to process of convolution.The data for projection obtaining is registered as sonar chart (sinogram), wherein, utilize along the pixel number of an axle (being level in this case) and source angle (being vertical in this case) array data in array along another axle.Then data are passed to one group of rear-projection summation processor elements 54 concurrently from selection piece 53.Use has precalculated coefficient for selecting essential convolution X ray data and for the look-up table of the weighting factor of rear-projection and summation fast, processor elements 54 is mapped to hardware.Format piece 55 is obtained the data of the image file that represents single reconstruct from multiple processor elements 54, and final output image data is formatted into the form that is suitable for the 3-D view that produces suitable format on display screen.For real-time or off-line are checked, can produce fast enough this output for the image that will produce in real time, thus, this system is called as real-time tomography (RTT) system.
In the present embodiment, multipath transmission piece 52 is coded in software, selection piece 53 and format piece 55 is coded in firmware, and processor elements is mapped in hardware.But according to the demand of particular system, each in these parts can be that hardware can be also software.
With reference to Fig. 5, then process the final output image of every width for each luggage and articles by the threat detection processor 60 in disposal system 30, this threat detection processor 60 is configured to determine whether the luggage and articles that are imaged represent threat.In threat detection processor 60, the tomography X view data 62 of input is passed in one group of low-level parameter extractor 63 (level 1).Parameter extractor 63 is identified the characteristics of image such as the area of constant gray level, texture and statistical information.Some extraction apparatuss act on 2 single dimension images or the data of section, and some act on 3 d image, and some act on sonar chart data.Possible in the situation that, each extraction apparatus acts on same group of input data concurrently, and each extraction apparatus is configured to carry out different processing and operates and determine different parameters.In the time that processing finishes, the parameter of being determined by parameter extractor 63 is passed to one group of decision tree 64 (level 2).Below provide the details of the parameter of extraction.Decision tree 64 is obtained respectively a large amount of (being generally all) low-level parameters, and by the relevant each more information of high-level of statistical information structure, as the information of the volume about adjacency.Upper in highest level (level 3), database search device 65 becomes to represent to exist " redness " the probability P r (threat) threatening and " green " the probability P r (safety) that represents to be examined article safety by the Parameter Mapping of the higher levels producing in level 2.Disposal system 30 utilizes these probability that scanned article are assigned to suitable security class, and produces automatic sorting control output.This automatic sorting control output can for represent article be assigned to release (clear) classification first " green " output, represent that automatic sorting that article are assigned to second " redness " output of " not releasing " classification or represent to implement to have enough reliabilities is to be assigned to article the 3rd " amber " output of classification of " releasing " or " not releasing ".Specifically, if Pr (safety) higher than predetermined value (or Pr (threat) is lower than predetermined value), has generation the automatic sorting output of first signal form so, represent that article should be assigned to green channel.If Pr (threat) higher than predetermined value (or Pr (safety) is lower than predetermined value), has generation the automatic sorting output of secondary signal form so, represent that article should be assigned to red channel.If Pr (threat) (or Pr (safety)) between two predetermined values, has generation the automatic sorting output of the 3rd signal form so, expression can not be assigned to article red channel or green channel.Also can be other output signals by probability output.
The parameter that will be determined by parameter extractor 63 is general tie up with 2 or the each independent region of 3 d image in the statistical study of pixel relevant.For each the independent region in recognition image, use statistics edge detection method.The method starts in a certain pixel, then checks whether adjacent pixel is the part of the same area, thereby outwards moves along with region growing.In each step, determine the mean intensity in region by the mean intensity of the pixel in zoning, and, the intensity of the next pixel adjacent with this region is compared with this mean value, to determine for the pixel in this region to be added whether its intensity enough approaches this mean value.In this case, determine the standard deviation of the image pixel intensities in region, and, if the intensity of new pixel is in this standard deviation, so it is added in this region.Otherwise, it is not added in this region, and, this by this region edge limited for the pixel in this region and be examined and be not added to the border between the pixel in this region.
Once image has been divided into multiple regions, parameter that so can measured zone.A this parameter is the measurement of the variance to the image pixel intensities in region.If it is higher, this piece material (lumpy material) of for example finding in homemade bomb that may express possibility, and if variance is lower, this may represent the homogeneous material such as liquid.
Another measured parameter is the deflection situation (skewedness) of the distribution of the pixel value in region, determines this deflection situation by the histogrammic deflection situation of measuring pixel value.Gaussian distribution (without skewed distribution) represents that the material in region is uniformly, and the distribution of high deflection represents the unevenness in region.
As mentioned above, these low-level parameters are upwards delivered to decision tree 64, in these decision trees 64, build the more information of high-level by the parameter of determined more high-level.The parameter of a this more high-level is the surface to volume ratio in the region of identification.Another is the measurement of similar degree, and this similar degree is the shape in region and is stored in the cross correlation between the shape of template in system in this situation.Shape of template is configured to the shape corresponding to the article with security threat such as gun or detonator.Determine by these high-level parameters the threat level being caused by the object to be imaged as explained above.
With reference to Fig. 6, online (in-line) real-time tomography baggage sorting system comprises the scanning system 6 of Fig. 1, and transmitter 20 is through this scanning system 6.In the downstream of scanning system 6, sorting equipment 40 is configured to receive each luggage from transmitter 20, and they are moved to and are released or " green " channel transfer device 42 or do not release or " redness " channel transfer device 44.By via operation circuit 46 from the automatic sorting output signal of disposal system 30 and by controlling sorting equipment 40 from the signal of workstation 48 (sorting equipment 40 is connected to workstation 48 via circuit 45), automatic sorting output signal represents whether disposal system 30 is the decision of releasing about article.The signal determining from the image of scanning system 6 with from the expression name red and green probability and disposal system 30 of disposal system 30 is also fed to workstation 48.Workstation is configured to show image on screen 47, makes operating personnel can see them, and the demonstration that provides indication green and red probability and nominal automatic sorting to determine.The user at workstation place can look back image and probability and automatic sorting output, and, if the decision of scanning system is article to be assigned to redness or green classification, determine so it is accept or overthrow this decision, or, if it is article to be assigned to " amber " classification that scanning system determines, determine whether to input so this decision.Workstation 48 has and makes user to input 49 to the user of sorting equipment 40 transmitted signals, and this signal can be sorted device and be identified as the decision of overthrowing scanning system.Be sorted device reception if overthrow signal, sorting equipment is overthrown the decision of scanning system really so.Overthrow signal if do not received, if or in fact receive the confirmation the confirmation signal of the decision of scanning system from workstation, the decision of sorting equipment based on scanning system sorted article so.If sorting system receives " amber " signal relevant with article from scanning system, it is assigned to these article " redness " classification that will be placed into red channel at first so.But, if before it sorts article it receive indication article from workstation should be in the input signal of " green " classification, so it by taxonomy of goods to green channel.
In the modification of the system of Fig. 6, sorting can be completely automatically, makes disposal system provide in only two kinds of sorting outputs " releasing " and " not releasing ", thereby article are assigned to green channel or red channel.For disposal system, also can determine an only probability P r (threat) by a threshold value, and whether higher or lower than threshold value, article are assigned to in two classifications according to this probability.In this case, distribution is still provisional, and operator still has the right to choose of overthrowing automatic sorting.In another modification, in the situation that not having user to input, use the automatic classification of scanning system to distribute as final distribution at all.This provides a kind of full-automatic sorting system.
In the system of Fig. 6, sweep velocity and transmitter speeds match, make to move luggage from loading area (at loading area, luggage is loaded onto on transmitter 20) through scanning system 6 by constant speed, and moved on sorting equipment 40.Transmitter 20 is extended distance L between the outlet of scanning system 6 and sorting equipment 40.During the distance L of advancing on transmitter 20 at luggage and articles, operator's observable is examined the view data of article and the initial category determined by scanning system is distributed, and confirms or the automatic decision of refusal RTT system.In general, luggage then can be accepted to releases on passage and forwards to prepare transportation, or is denied to and does not release on passage further to investigate.
Multifocal in system at this RTT, RTT scanning element 8 can, by the operation of highest line Lee tape speed, not need luggage to queue up or other steering mechanism thus for best system operation.In the integrated system such as this system, the limited handling capacity of conventional rotational source system is obvious constraint.This often means the CT machine of placing concurrently multiple routines, and uses complicated baggage handling system examine article are switched to next available machine.By the configuration of Fig. 6, can avoid this complicacy.
With reference to Fig. 7, the second embodiment of the present invention comprises redundant system, and in this redundant system, two RTT scanning systems 70,72 are in series placed on same transmitter 74, if make a system exit service, another can continue luggage scanning so.In any situation, transport tape 74 can continue across two scanning systems 70,72 under the operation tape speed of standard.
With reference to Fig. 8 a, in the 3rd embodiment, be provided with the more complicated redundant system that operates concurrently two RTT systems 82,84.The first master enters transmitter 86 and takes all article that will be sorted to first sorting equipment 88, and this first sorting equipment 88 can be sent to article in any in two other transmitters 90,92.Whether each in these two transmitters 90,92 is through by scan articles and make it possible to for corresponding one that releases in the scanning system 82,84 that article make decision.In each in two transmitters 90,92, be provided with another sorting equipment 94,96, this sorting equipment 94,96 is configured to baggage sorting to ' green channel ' transmitter 98 sharing for transmitting forward, or in the situation that these article are not released, be sorted on ' red channel ' transmitter 100, on this ' red channel ' transmitter 100, it can stand further investigation.In this configuration, can be by speed operation input transmitter 86 and ' green channel ' transmitter higher than RTT transmitter speed, twice that generally reach this speed.For example, in this case, main ' green channel ' transmitter that enters transmitter 86 and share moves with the speed of 1m/s, and the speed that scan transfer device 82,84 is 0.5m/s with the half of this speed is advanced.Certainly, can expand this system by more parallel RTT system, the ratio that makes winner enter the speed of transmitter and the speed of scanner transmitter equals or is substantially equal to the quantity of parallel scanner, although may become unreliable being greater than sorting equipment under about 1m/s master transmitter speed.
With reference to Fig. 8 b, in another embodiment, baggage sorting system comprises many RTT scanner 81b, 82b, 83b, generally in a system, reaches approximately 60, and each is associated with corresponding check-in platform.Sorting equipment 84b, 85b, 86b are relevant to each RTT scanner, and luggage is transferred to its relevant sorting equipment from each RTT scanner on transmitter.Each sorting equipment 84b, 85b, 86b release channel transfer device 88b or shared refusal channel transfer device 87b by baggage sorting to what share in response to the signal from its scanner.On refusal channel transfer device 87b, be provided with another standby RTT scanner 89b, this standby RTT scanner 89b has that luggage can be stayed to refusal channel transfer device 87b upper or send it to the relevant sorting equipment 90b that releases channel transfer device 88b.
Under normal operation, each in single pass instrument 81b, 82b, 83b sorts luggage, and standby or redundancy scanner 89b provide further inspection to the article that are sorted in refusal passage.If this scanner determines that luggage and articles representatives does not have or enough low threats, it is sent to these luggage and articles to release passage so.If in single pass instrument one is inoperative or break down, its relevant sorting equipment is configured to all baggage sortings from this scanner to refusal passage so.Then, standby scanner 89b scans these all luggage and is releasing passage and refusal is controlled its sorting between passage.This makes check-in platforms all when fault scanning instrument is keeped in repair or changes can both continue to work.
With reference to Fig. 8 c, in another embodiment, the luggage of each from check-in in platform is sent to Central Circuit via multiple independent transmitters or endless belt conveyer 81c is upper, and on this travelling belt 81c, luggage circulates continuously.Many sorting equipment 82c, 83c, 84c are configured to respectively the luggage and articles of self-loop 81c in the future and are sent to the respective transmissions device that is directed to corresponding RTT scanner 85c, 86c, 87c.Sorting equipment 82c, 83c, 84c are scanned instrument control system, to control, luggage and articles are fed to each the speed in scanner.From scanner, transmitter is sent to all luggage and articles the shared outlet transmitter 88c that is directed to another sorting equipment 89c.By all scanners, it is controlled to each in luggage and articles is sorted releasing between passage 90c and refusal passage 91c.
In order to follow the tracks of the movement of each luggage and articles, its position on transport tape that each article are given 6 digital ID and recorded in the time that these article enter system for the first time.Therefore scanner can be identified in any one moment and scan which part luggage and articles, and scanning result is associated with suitable article.Sorting equipment therefore also can identify each luggage and articles and the scanning result based on them sorts them.
The quantity of scanner and the speed of transmitter of configuration in native system, if make one in scanner inoperative, so remaining scanner can be processed from check-in platform and be fed to all luggage the 81c of loop.
In the modification of the present embodiment, select sorting equipment 82c, 83c, 84c which article is sent to each scanner not by scanner control, but be configured to respectively select the article of self-loop 81c, with the speed by predetermined, they are fed to corresponding scanner.
With reference to Fig. 9, according to the networked system of another embodiment comprise three with the similar scanning system 108 of scanning system and four operator workstations 148 of Fig. 6.Video image output from three RTT scanning systems 108 is connected with the real-time disk array 109 of the volatile storage that is provided for raw image data to redundancy video switch 110 by the point-to-point video link of corresponding high bandwidth.Disk array 109 is connected with each in workstation 148 again.Therefore video switch 110 can be sent to any workstation 148 from its temporary storage by the raw video image of each output from scanning system 108, can utilize this raw video image to produce 3 three-D video images of can off-line watching in this workstation 148.From being connected for and the output of automatic sorting distributing signal and the conventional Ethernet switch 112 of redundancy of red/green probability signal of scanning system, this Ethernet switch 112 is also connected with each in workstation.Ethernet switch is configured to each in distributing signal by probability signal and sorting and is switched to same workstation 148, as the vision signal being associated.This allows the view data from multiple machines to receive together with giving the probability of this distribution with automatic distribution on operator workstation 148 groups (bank), in this group, operator can monitor the execution of baggage screening system and determine the destination of being composed with the luggage of amber threat level.
As an alternative, a kind of networked system comprises the single scanning system 108 and the workstation 148 that are connected with server.Video image output from scanning system 108 is connected with the real-time disk array 109 that volatile storage is provided for raw image data.Disk array 109 is connected with workstation 148 again.Probability signal is sent to workstation 148 with distributing signal output together with will being exported by the associated video image of operator monitor.The single scanning system of networking can be a part with the networked system of multiple scanning systems.
With reference to Figure 10 and Figure 11, in another embodiment, online (in-line) scanner has the just transport tape grown 160 the same as main scattering protective cover 162.In this stand-alone system configuration, be placed to transport tape 160 for the article that check, and these article are loaded onto in system.Then by scanner machine 164 scan articles and produce image.In conventional system, before the computerized axial tomography projection of the plane of the selection in object, usually with the simple x-ray system that transmits, article are carried out to Ported reflex, to identify possible threatening area.This application is only for real-time multifocal apart from system.Here do not use Ported reflex, and will obtain the true three-dimension image of whole article.
In certain embodiments, the track of multifocal source point in x-ray source will extend in adding the arcs on the angular range of fan beam angle (generally in the scopes of 40～90 degree) at 180 degree only.Advantageously, select the quantity of discrete source point to meet Nyquist sampling thheorem.In certain embodiments, as the embodiment of Fig. 1, use the source point of 360 complete degree rings.In this case, for given sweep speed, residence time of each source point increases, and exceedes the configuration of 180+ fan beam, and this improve reconstructed image signal to noise ratio (S/N ratio) aspect be favourable.
The beam scanner system of Fig. 1 is integrated scanning instrument system, and this is because accommodate control, processing, power supply and cooling unit 18,30,32,34 in the unit with scanning system 8 and mask 22.With reference to Figure 12, be provided with in another embodiment modular system, in this modular system, some or all in control, processing, power supply and cooling frame 218,230,232,234 are positioned as away from comprising the multifocal scanning element 208 apart from x-ray source and sensor array.Advantageously use modular design so that install, this processes in the environment of hall especially favourable at luggage, and in this environment, system can be suspended on ceiling or in accessing limited region.As an alternative, whole system can be configured to have the integrated unit of the multiple sub-components unit being co-located in single shell.
In some embodiment including the embodiment of Fig. 1, use single X-ray detector ring.Even if it is also comparatively cheap building and enough noise performances are provided by simple fan beam image reconstruction algorithm under higher image scanning speed.In other embodiment (particularly for larger Image Reconstruction circular diameter), preferably use many ring sensors array, this many ring sensors array has the sensor group of along the axle that departs from source of system multiple circles that separate, disposed adjacent one another or part circular.This makes it possible to use more complicated cone-beam image reconstruction algorithm in disposal system.Use many ring sensors can increase the residence time of each source point, obtain the improvement that therefore larger integrated signal size also causes the signal to noise ratio (S/N ratio) of reconstructed image.
The center that uses the design of above-described embodiment based on the multifocal computed tomography system apart from x-ray source is the angular velocity of rotation of radioactive source and the relation through the speed of the transmission system of scanner.Under the static limiting case of transmitter, the thickness of the image slice of reconstruct is determined by the area of the size of X ray focal length and each element of X-ray detector array completely.Along with transmitter speed is from zero increase, inspected object will be cut into slices through imaging in the rotary course of X ray beam, and, the direction along slice thickness is introduced in the image of reconstruct to add fuzzy.In the ideal case, x-ray source rotation will be very fast compared with transmitter speed, make will be minimized along the fuzzy of slice thickness direction.
For the object that the high probability that is examined threat materials in article and object is detected, good radioactive source angular velocity of rotation and the ratio of transmitter linear velocity are provided for baggage check based on the multifocal computed tomography system apart from x-ray source.As example, in the embodiment in figure 1, as common in airport system, transmitter speed is 0.5m/s.Radioactive source can be realized per second around the rotation of 240 sources of transmitter, therefore inspected object in scanning process by the distance of the mobile 2.08mm that cuts into slices through imaging.Having in the conventional system of the per second 4 sources rotations that turn, inspected object under identical tape speed by scanning process through the cut into slices distance of mobile 62.5mm of imaging.
Fundamental purpose for detection of the check system of threat materials is accurately to detect the existence of threat materials and in the time there is no suspicion, let slip every other material.In scanning process because transmitter moves fuzzy larger along slice direction causing, the more out of true of image density of the larger and reconstruct of the partial volume artefact (artefact) in reconstructed image pixel.The precision of the image density of reconstruct is poorer, and system more likely provides alarm and real threat materials do not given the alarm non-threat materials.Therefore,, compared with the x-ray system of conventional machinery rotation, can under higher transmitter speed, provide the threat detection capabilities of remarkable enhancing based on multifocal real-time tomography (RTT) system apart from x-ray source technology.
Owing to using the arc anode of expanding multifocal in x-ray source, therefore can carry out switch to electron source, it is jumped on the overall length of anode, rather than scan successively to imitate the machinery rotation of observing in conventionally calculation tomograph system.Advantageously, in order to make the transient heat load minimizes on anode, X ray focal length by by switch so that current anode radiation position maximize to the distance of the radiation position before all.Thereby making to move due to transmitter in the process that the partial volume effect causing minimizes the pixel precision that further improves reconstruct, this instantaneous expansion of X ray launching site is favourable.
The higher temporal resolution of RTT system allows to realize higher precision level in automatic threat detection.By this higher precision level, can in unserviced pattern, operate RTT system, thereby produce simple two State-outputs indications, a kind of state with green or release distribute corresponding, another kind of and redness or not release distribution corresponding.Green bag is released for transmission forward.The higher threat level of red bag representative, and should coordinate and forbid this passenger's travelling with passenger.
Other embodiment of the present invention will be described now, and in these embodiments, the data relevant with the scattering of X ray and the data relevant with the X ray being transmitted are recorded and for analyzing scanned luggage and articles.
With reference to Figure 13, when the beam 300 of X ray is during through object 302, some in X ray directly see through it and leave object, and this object is advanced along entering with these X ray the direction that the direction of object is identical.Some in X ray are scattered by scatteringangleθ, and scatteringangleθ is direction poor that they enter the direction of object and they and leave object.As everyone knows, can there is the scattering of two types: concentrate on 5 °, be generally the relevant or Bragg diffraction around of scattering angle of 4～6 °, and X ray is by the incoherent or Compton scattering of larger scattered through angles.Bragg diffraction is along with the atomic number linearity of object increases and obedience following formula:
nλ＝2dsinθ
Wherein,
N is integer
λ is the wavelength of X ray
D is the interatomic disance in object.
Therefore, the amount of Bragg diffraction has provided the information about the atomic structure of object.But it does not change smoothly along with atomic number.
The amount of Compton scattering depends on the electron density of object and changes smoothly with it, and therefore, the scattered quantum under larger scattering angle has provided the information about the electron density of object, and has provided thus the information about its atomic number.
With reference to Figure 14, security sweep system according to another embodiment of the present invention comprises identical multifocal apart from x-ray source 410 with Fig. 1 and identical circular detector array 412 and transmitter 420 same and in Fig. 1.But in the present embodiment, system comprises another cylinder detector array 422, this cylinder detector array 422 is extended around transmitter with the radius identical with circular detector array 412, but the opposite side in radioactive source 410 vertically.Although circular detector array is configured to detect the X ray that sees through object 426, cylinder detector array 422 is configured to detect the X ray of scattering in object.Scatter detector array 422 is made up of a large amount of circular array of detecting device or ring 422a, 422b, and detecting device in each ring separates equably around transmitter, makes them be configured to the axially extended many craspedodromes along scanner.
Detecting device in scatter detector array 422 is energy resolution detecting device, makes can produce with each X ray reciprocation of each detecting device the detecting device output of the energy of indication X ray.Can be by the broad-band gap III-V such as GaAs, HgI, CdZnTe or CdTe or II-IV semiconductor material, manufacture these detecting devices such as the narrow gap semiconductor of Ge or such as the compound scintillation detector of the NaI (Ti) with photomultiplier reader.
With reference to Figure 15, before scatter detector 422, be provided with collimating apparatus 428.Collimating apparatus 428 provides obstacle, and this obstacle prevents that X ray from arriving each detecting device, unless X ray is from specific receive direction.As can be seen from Figure 16, for each detecting device in array 422, receive direction is through the center longitudinal axis X-X of scanner.But as can be seen from Figure 15, receive direction is not vertical with axle X-X, but tilt to the plane of detector rings 422a, 422b with the angle of approximately 5 ° along the direction towards radioactive source 410.
With reference to Figure 15, be appreciated that X ray in any in the detecting device that incides array 422 must be the thinner imaging volume the line of the path from being positioned at X ray beam and the receive direction from detecting device 422 corresponding boy's volume scattering out.For the X ray of any coherent scattering, detect that the axial location of its detecting device is determined the distance of the movable X ray source point by there is scattering.The detecting device that approaches most vertically radioactive source 410 is lighted scattering from movable x-ray source and is obtained X ray farthest detecting.For example, will be by apart from the radioactive source 410 detecting device detection far away than the X ray of scattering from a z (it is farther apart from movable X ray source point) from the X ray of some x scattering of the X ray source point 410a that approaches most activity.Therefore,, in any one moment, in the time that movable X ray source point can be identified, detect that the axial location of the detecting device of the X ray of scattering can be used for determining the scattering position along X ray beam direction.
It can also be appreciated that in order to make system works from Figure 15, it is important, should be along axially very narrow the focusing X-ray beam of scanner.Beam will allow this location of coherent scattering event along horizontal expansion (along laterally using fan beam to launch).
With reference to Figure 16, due to the axle of collimating apparatus 428 alignment scanning instrument, therefore, the X ray from movable source point 410a that stands coherent scattering detects the detector line 422a that is only positioned at a side relative with movable source point scanner axle, and, be focused in how narrow degree according to collimating apparatus, may be detected by one or more row in nearly its row of arbitrary side joint.If X ray is restricted to not only straight but also narrow " form of a stroke or a combination of strokes " beam, so, owing to ending by being collimated device 428 compared with any X ray of incoherent ground of wide-angle scattering, therefore detected at all is less than any this X ray.Arrow ' a ' in Figure 16 shows the example of this X ray.But, if produce the fan beam that sees through the X ray of imaging volume section developing along the direction vertical with scanner axle from movable source point 410a, point to so the detecting device that the X ray of scanner axle further away from each other can stand non-coherent scattering and arrive the either side of the row 422a relative with movable source point.Arrow b and c show the example of these X ray.It should be noted that in order to arrive any detecting device 422b, must in the plane through scanner axle and this detecting device 422b, scattering events occur.This means, for given movable source point and specific detecting device, the position of the scattering events of detected X ray can be identified as being positioned in the plane through scanner axle and this detecting device.If determine the accurate location of scattering events, need so other information.For example, if can obtain from for example tomographic imaging data about the information of the position of the object in imaging volume, so, as described in more detail below, scattering can be relevant to most probable object.
By Bragg diffraction data, for the scattering events of each detection, the combination of X ray energy and scattering angle can be used for determining the interatomic disance d of the material that scattering events has wherein occurred.In fact, can suppose that scattering angle is constant, and distinguish different materials with energy.For Compton scattering, provide the indication of the density of the material in this volume from the level of the scattering of each volume of scattering volume.Also can determine Compton scattering and the ratio of coherent scattering and used as another parameter of material that characterizes imaging object.
Due to the shorter residence time for each X ray source point, therefore the quantity of the scattered x-ray detecting of each source point is always considerably less, is generally less than five.In order to form rational coherent scattering signal, must collect the scattering data of all source points in tomographic scan, the then result of each subvolumes of accumulation imaging volume.For thering is the scanner of 500 source points and the mean value of a coherent diffraction scattering result of the every subvolumes of each scanning, so, after one group of data of accumulation, every subvolumes will have 500 results corresponding to 500 scattering events relative and in this sub-volume.Typical sub-volume occupies the area of several square centimeters in imaging plane, and ulking thickness is several millimeters.
Referring now to Figure 17, be configured to accumulation and comprise and each relevant multichannel analyzer (MCA) 500 in detecting device 422 from the data acquisition system (DAS) of the data of the scatter detector array 422 of the scanner of Figure 14～16.Each MCA 500 is configured to receive the output signal of self-detector, and distributes the each X ray detecting to one in a large amount of X ray energy ranges or passage, and the signal of the energy range that falls into of the X ray that detects of output indication.Multiplexer 502 is configured to receive each the output from MCA 500.The look-up table 504 wherein with multiple entries is also provided, and these entries are for given source point and the detecting device sub-volume in the imaging volume of X ray of having identified wherein scattering.This system also comprises the video memory 506 that comprises a large amount of memory block 508, and each in these memory blocks 508 is relevant to the each subvolumes in scanner imaging plane.
Under the guidance of look-up table 504, automatically data are loaded in each memory block 508 by multiplexer 502.Look-up table was mounted with by each combinatorial mapping of detecting device 422 and MCA 500 coefficient to corresponding picture position 508, one of each x-ray source position lookup table entries before scanning.Those pixels (being detecting device 422) in forward (direction of substantially advancing from radioactive source before any reciprocation in photon) are assumed that with the little beam angle of approximately 4～6 degree and record coherent scattered photons.Be not assumed that in those pixels 422 of forward the non-coherent scattering photon that record causes due to compton effect,scattering.Thus, video memory 506 is actually the position in " three-dimensional "-two dimension representative image, and third dimension degree is kept for the scattering energy spectrum of coherent scattering (least-significant byte) and non-coherent scattering (most-significant byte).Look-up table 504 also, by about being the data type indication multiplexer 502 that each MCA 500 collects when each projection, makes to fill suitable storage space.
Once collect scattering data for given scanning, just data be sent to the above main RTT data acquisition system (DAS) 512 with reference to Fig. 4 explanation, and by projection sequencer 510, these data synchronizeed with main RTT data acquisition system (DAS) 512.Thus, the view data of reconstruct and scattering data are delivered to threat detection system simultaneously, and this threat detection system can be determined suitable analysis parameter with it.
For each scanning, can produce and the X ray of each pixel of the image relevant data that decay from the tomographic image data of transmission detector 412, these data are corresponding with the corresponding sub-volume of tomographic imaging volume again.As illustrated with reference to Fig. 4 above, obtain this data.The data relevant with the amount of the coherent scattering in each sub-volume are provided as described above and the relevant data with the amount of non-coherent scattering in each sub-volume from the data of scatter detector 422.Therefore can with the similar threat detection processor of threat detection processor of Fig. 5 in analyze this data.In this case, the parameter of the data of extraction can be relevant with the combination of the data of view data or scattering data or two or more types.The example of parameter of extracting from data is coherent scattering with the ratio of non-coherent scattering, from the definite material type of coherent scattering data, from the correlationship of the definite density of material of non-coherent scattering data, CT image pixel value and scattering data.And, also can determine the scattering data parameter corresponding with the parameter illustrating for transmission data above.
With reference to Figure 18, in another embodiment of the present invention, be configured to measure X ray transmission for generation of the transmission detector 512 of tomographic image data in different energy ranges.Realize this point by thering are two groups of detecting device 512a, 512b forming respectively around the ring of transmitter.These two groups are positioned at different axial locations along the direct of travel of transmitter, and in this situation, these two groups are adjacent one another are vertically.First group of 512a do not have wave filter before it, but second group of 512b has the metal wave filter 513 between it and x-ray source 510.Therefore first group of detecting device 512a detect the X ray seeing through in wider energy range, and second group of 512b only detects X ray in the narrower part in high-energy end of this scope.
Along with the article that will be scanned move along transmitter, can use first group of detecting device 512a by its each thin volume or section run-down, then use second group of 512b again to scan.In the illustrated embodiment, use same radioactive source 510 to scan two adjacent volumes simultaneously, make by corresponding each the data of collecting in these two volumes in detector set 512a, 512b.Through two groups of detecting devices and be scanned after twice, can use two different X ray energy ranges to form two groups of view data, the transmission data (and comprising thus attenuation data) of each pixel that each image comprises image at the volume of article.Can, by deduct the view data of the second detector set 512a from the view data of the first detector set 512b, these two groups of view data be combined, obtain the corresponding view data of low-energy X-ray component.
Can record the X ray transmission data of each single energy range and such as the difference between high-energy and the data of low-energy two different range for each pixel of image.Then can utilize these data to improve the precision of CT image.Also can be used as another parameter in threat detection algorithm.
Be appreciated that the method that can use other is with the transmission data of the X ray energy of acquisition different range.In the modification of the system of Figure 18 and Figure 19, can in two detector set, use balanced filter.Selective filter, makes to exist the narrow energy window of being passed by they both sides.Then the view data of two groups of detecting devices capable of being combined is to obtain the transmission data of this narrow energy window.This makes it possible to obtain chemical specific imaging.For example, can be by using the wave filter balancing out around calcium K edge energy to produce bone specific image.Obviously, can in threat detection algorithm, effectively use this chemistry particular data.
In another embodiment, do not use each independent wave filter, and use two groups of detecting devices for different-energy X ray sensitivity.In this case, use stacked detecting device, these detecting devices comprise thin front detecting device responsive to low-energy X-ray and that allow higher-energy X ray to pass, and for the thick rear detecting device of the high-energy X ray sensitivity through front detecting device.Equally, can use the attenuation data of different-energy scope so that energy special image data to be provided.
In another embodiment, two kinds of different X ray beam energies using the different tube voltage by use for example 160kV and 100kV in x-ray source to realize are carried out twice sweep to each section of object.The X-ray energy spectrum that different energy can obtain being offset toward each other.Because power spectrum is relatively flat in part energy scope, therefore power spectrum is similar on the mass part of this scope.But a part for power spectrum is by marked change.The movement images that therefore, can use two kinds of tube voltages is to be identified in the object part of the marked change that decays between this two width image.Therefore this identify the image area with high decay in the narrow power spectrum part changing between image.Therefore this is to obtain each the alternative of energy particular decay data being scanned in sub-volume in volume.
With reference to Figure 20, in another embodiment of the present invention, by the X-ray tube of target area 602,604 with two kinds of different materials, anode 600 being set, produce two kinds of different X-ray energy spectrums.In this case, for example, anode comprises the copper base 606 with a tungsten target area 602 and a uranium target area 604.Electron source 610 has a large amount of source point 612 that can be activated individually.Couple positioned opposite in the path of electron beam 616 has pair of electrodes 612,614, and this electrode 612,614 can be controlled as opens and cut off electric field to control the path of electron beam, makes its clash into one or the other in target area 602,604.The power spectrum of the X ray producing on anode changes striking according to electron beam 616 on which in target area.
The present embodiment uses the similar x-ray source of x-ray source with Fig. 1 a, and different target areas is formed as the parallel band extending along anode 27.For each movable electronics source point, according to using which kind of target material, can produce two kinds of different X-ray spectrums.Radioactive source can be configured between two target areas at each electronics source point, switch in the time that it is movable.As an alternative, can carry out the scanning twice along anode 27, once for a kind of target material, once for another kind.In any situation, may need other Electron Beam Focusing wire once only to irradiate one or the other target material to guarantee electron beam.
According to the angle of extracting X ray beam from anode, can be configured in some cases detect through same imaging volume the detector array that shared from the beam of two target areas 602,604.As an alternative, they can be configured to detect through the adjacent section of imaging volume and by each independent detector array.In this case, can by with the similar mode of configuration of Figure 18 at article together with transmitter through twice of the various piece of out-of-date scanning imagery article.
With reference to Figure 21, in an embodiment also, two detector arrays adjacent one another are are in the axial direction set in single scanner, the detector array of detector array 710 and Fig. 1 is corresponding and be configured to form RTT image, and another detector array 712 has higher resolution and is configured to produce the high resolving power projected image of scanned object.In the present embodiment, high-resolution detector array 712 comprises two parallel linear arraies 714,716, and each in these two linear arraies 714,716 is configured to detect the X ray of different energy, makes to produce double energy projected image.In the embodiment of Figure 22, high resolution ratio array 812 comprises two stacked arrays, that is, what be positioned at top is configured to detection compared with low-energy X-ray and to the transparent thin array of higher-energy X ray, and is positioned at the thicker array that is configured to detect higher-energy X ray of below.In both cases, it is enough close vertically that two detector arrays are all configured to, can detect the X ray from the single linear array of source point.
For projected image is provided, in the time only having source point movable, all detecting device capture-datas that need to be from high resolution ratio array 712,812.With reference to Figure 23, in order to realize this point, each detecting device 718,818 in high resolution ratio array is connected with integrator 750.Integrator comprises the amplifier in parallel with capacitor 754 752.Between detecting device 718 and amplifier 752, input switch 756 is set, input terminal two ends at amplifier arrange reset switch 758, connect another reset switch 759 at capacitor 754 two ends, and between integrator and analog to digital converter ADC, multiplexer switch 760 is set.
In operation, in the time not needing detecting device 718 movable, close all switches except multiplexer switch 760.This guarantees that capacitor 754 is not charged and keeps intact.Then, in the time requiring detecting device to collect the beginning of period of data, close two reset switches 758,759, make any X ray being detected by detecting device 718 to cause the increase of the electric charge on capacitor 754, this can obtain the integration of the signal of self-detector 718.In the time finishing for the period of data acquisition, open input switch 756, make capacitor will keep charging.Then,, in order to read integrated signal from integrator, close output switch 760 so that integrator is connected with ADC.Provide simulating signal to ADC like this, this simulating signal determined by the level of the electric charge on capacitor 754, and therefore indicates the quantity of the X ray that detecting device 718 detects during the period being connected with integrator.Then ADC converts this simulating signal to digital signal for being input to data acquisition system (DAS).In order to produce single width projected image, when one in X ray source point when movable, use all high-resolution detector to collect data simultaneously.
With reference to Figure 24, in another embodiment, each detecting device 718 is connected with in parallel two integrator 750a, 750b, and each in these two integrator 750a, 750b is identical with the integrator of Figure 23.Output from these two integrators is connected with ADC via their output switch 760a, 760b.This makes each integrator can be configured to come in different some upper integrals the signal of self-detector 718 in the scanning of x-ray source, and the data of therefore collecting independent image, this two width image by different X ray source points from different angles.For example, can use it to produce several projected images from orthogonal directions, these projected images can be used for building high resolving power 3 d image, by this high resolving power 3 d image, can in three dimensions, determine the position that is imaged the feature in parcel.
Because high-definition picture can help identification such as the article that need high-resolution of filament, in the time of it and RTT image combining, can be therefore useful.
